Claude Opus 4.6 fe5896be2d feat: initial Telepathy Elixir port — GenServer + JMAP fetch loop
Adds the Telepathy email communication layer as an OTP subtree:

- Telepathy.JMAP: GenServer that discovers Fastmail JMAP session,
  periodically polls inbox for new emails, and provides send_email/3.
  Uses :httpc (no external HTTP dep). Deduplicates via seen_ids MapSet
  seeded from existing MessageStore entries.

- Telepathy.MessageStore: JSONL-backed message persistence, compatible
  with the existing Python messages.jsonl format. Supports store, unread,
  mark_read, list, count operations.

- Telepathy.Supervisor: rest_for_one supervisor (MessageStore then JMAP).

- Conditionally enabled via config (:telepathy, :enabled). Disabled in
  test env. Can be disabled at runtime via TELEPATHY_ENABLED=false.

Validated against live Fastmail: session discovery, inbox fetch (20
emails), message storage all working.

OTP Application for Symbiont — the self-sustaining AI orchestrator.
Supervision tree (dev/prod):
Symbiont.Supervisor
├── Task.Supervisor (Symbiont.TaskSupervisor)
├── Symbiont.Ledger — append-only cost log
├── Symbiont.Queue — persistent task queue
├── Symbiont.Engram — cross-session memory (SQLite)
├── Symbiont.Heartbeat — periodic health checks + queue processing
├── Symbiont.Telepathy.Supervisor — email communication layer (if enabled)

└── Bandit (Symbiont.API) — HTTP API
In test mode, the supervisor starts empty — tests manage their own processes.
## Graceful shutdown
Bandit is configured with a long ThousandIsland `shutdown_timeout` so that
in-flight `/task` requests (which can take up to 600s while Claude runs)
are not killed when systemd restarts the service. The Bandit child spec
also carries a matching `:shutdown` value so the OTP supervisor itself
waits long enough before forcing a kill.
The matching systemd unit must set `TimeoutStopSec=620` for this to take
effect end to end.
